4Pin IR Infrared Obstacle Avoidance Sensor Module

product description Description: The object is the induction output 0, the output 1 is not sensitive when the direct use of 3V and 5V microcontroller IO port connection. Sensing distance of 2-40 cm, distance, anti-interference ability. (Note: the infrared sensor can not detect all the objects get the same distance, different objects with different light reflectance objects closer to the darker the shorter detected distance, the sensor 2-40 cm is measured against the white wall) Speed, suitable for intelligent car obstacle avoidance, black and white line tracking, anti-theft, product counters, cutting lines, liquid level detection. This sensor is used black and white line tracking car running on white paper without black lines, can be used in concrete yellow complex environment, such as black line patrol track. As long as the color around the black line a bit lighter than black, eliminating the need for traditional action, so that the layout of the environment more easily. Sensor 3 ~ 6V power supply, suitable for a wide range of applications for 3V and 5V microcontroller system. When enable is enabled, the EN terminal equals "1" when the sensor is not operating and "0" when operating. Long jump to the sensor end cap (EN long "0") after the EN ground plug. Use jumper pin with jumper cap. Frequency adjustment potentiometer is used to adjust the infrared emission tube carrier frequency, because the integrated receiver 38KHZ especially when the carrier frequency is the most sensitive time. 502 resistance is shifted clockwise (ie, the emitter is at its maximum brightness) and then moved to the white wall resistance of 103
